Studi Eksperimental Pengaruh Kemiringan Sudut Terhadap Alat Destilasi Air Laut Memanfaatkan Energi Matahari

Abstract

Indonesia is one country that is in a tropical climate that promises sunshine of all time. The abundant potential of solar radiation can be utilized in a distillation device to convert sea water into fresh water. This research aims to build a distillation device as a provider of clean water. Test equipment is designed and built with black fiber material with a size of 1.25 m x 0.8 m with a 3 mm thick glass cover with a capacity of 3600 ml of sea water. To find out the effectiveness of the distillation apparatus, it was tested with three variations of slope angles namely 30 0 , 40 0 , and 50 0 . Tests carried out in the city of Medan. The testing method is done by evaporating seawater, evaporation occurs because of the absorption of heat from the sun through a solar collector's plate. The result obtained an effective slope angle is 30 0 with a production of 650 ml of fresh water. In addition to fresh water production, it is also known that the maximum sea water temperature is 73 0 C at 12:20 WIB, the radiation heat transfer rate is 92.86 Watt
